• HTML table with fixed headers?

  - by Cheekysoft

  Does anyone know a cross-browser CSS/Javascript technique to display a long html table such that the column headers stay fixed on-screen and do not scroll with the table body. Think of the "freeze panes" effect in excel. I want to be able to scroll through the contents of the table, but to always be able to see the column headers at the top.

• Conventions for order of parameters in a function

  - by Andy

  In writing functions my brain always spends a few milliseconds to check which order of parameters would be best for a given function. should I write: public Comment AddComment(long userID, string title, string text) Or probably: public Comment AddComment(string title, string text, long userID) Why not: public Comment AddComment(string title, long userID, string text) Do you follow any rules when ordering the parameters for your functions? Which parameter would you place first and which would follow?

• Is it possible to parameterize subversion repository URL with revision in Hudson?

  - by Vladimir Bezugliy

  I have a job in Hudson with Subversion as Source Code Management. But I do not want always to update working copy to HEAD revision. I need to have ability to choose SVN revision during start of this job. It is possible to parameterize build with revision number. But as far as I can see I cannot use parameter in repository URL. I can only hardcode revision. Is it true?

• BoundsChecker shows incorrect memory leak message

  - by Prabhu

  Hello All, I'm using BoundsChecker9.1 with visual c++. I have a class class Sample{ public: vector(AnotherClass) x; }. When I run my program the BoundsChecker tool reports all push_back() calls such as S.x.push_back(AnotherClass()) as memory leak.. Wouldn't all the elements in vector x will always be deallocated when the Sample class goes out of scope? If so, any idea about why BoundsChecker is showing them as memory leak?

• PRG Pattern and Sticky Forms

  - by Scott Christopherson

  I'm using the PRG pattern on a form of mine. I've never used this approach before and I'm trying to figure something out: Normally, I always just displayed the posted form again when there were validation errors and displayed POST values in the form (sticky form). However with the PRG pattern, the form is displayed after a redirect, so there aren't any POST values. So my question is, how can I implement the PRG pattern and still have sticky forms?

• In MVVM should the ViewModel or Model implement INotifyPropertyChanged?

  - by Edward Tanguay

  Most MVVM examples I have worked through have had the Model implement INotifyPropertyChanged, but in Josh Smith's CommandSink example the ViewModel implements INotifyPropertyChanged. I'm still cognitively putting together the MVVM concepts, so I don't know if: you have to put the INotifyPropertyChanged in the ViewModel to get CommandSink to work this is just an aberration of the norm and it doesn't really matter you should always have the Model implement INotifyPropertyChanged and this is just a mistake which would be corrected if this were developed from a code example to an application What have been others' experiences on MVVM projects you have worked on?

• gcc : Is using -Werror and -pedantic considered good practice?

  - by Helper Method

  I'm just digging into the gcc manual and some things are still unclear to me: When specifying a std, should I always use -pedantic in conjunction? When using -g, it the standard level sufficient or should I specify level 3, i.e. -g3? Is it good practice to use -Werror to promote all warnings to errors and -pedantic-errors to promote all pedantic warnings to errors?
